| Summary: | Заглавие с экрана The results of ab initio study of the bulk and surface electronic structure of the GdY2Si2 compounds (Y = Cu, Ag, Au) are presented in this work. Our electronic band structure calculations have shown that the silicon-terminated surface of GdY2Si2 bears two distinct two-dimensional electron states, one being a Shockley surface state, and the other - a surface resonance. We demonstrate that the appearance of the surface resonance state is caused by a layered crystal structure of the GdY2Si2 compounds. |
